Route surveying refers to surveying for the planning and construction of facilities built over a narrow and long distance such as roads, railroads, waterways, pipelines, transmission lines, and ropeways. The general route surveying method is an important process so that the center of the route is connected and staked, and vertical and cross-sectional surveys are performed along the center line to calculate the amount of construction work according to the slope and plan height of the route, and to prepare detailed drawings after skeleton surveying. If various basic drawings are calculated using an unmanned aerial vehicle for such route surveying, it is believed that the effects of shortening the process and reducing construction costs can be obtained. Therefore, this study attempted to contribute to the improvement of reliability in the application of route surveying using an unmanned aerial vehicle by deriving an optimal photographing technique by conducting route photography in various ways.

The purpose of this study was to investigate the dietary habits of obese and non-obese in Changwon city (n=369 workers). The implementation of the national dietary guidelines for Koreans was significantly lower in obese group than non-obese group (p<0.05). The rate of eating less than 10 minutes was significantly higher in obese group than non-obese group (p<0.05). The smoking rate of obese group was significantly higher than non-obese group (p<0.05). The rate of drinking (p<0.001) and drinking more than seven cups at a time (p<0.05) was significantly higher in obese group than non-obese group. 1 serving size of rice, beef, pork, and chicken (p<0.001) was significantly higher in obese group than non-obese group (p<0.01). Obesity showed negative correlations with the implementation of the national dietary guidelines for Koreans (r=-0.12, p<0.05) and the speed of meals (r=-0.13, p<0.05), and positive correlations with the smoking rate (r=0.12, p<0.05) and the drinking rate (r=0.17, p<0.01). The results of hierarchial multiple regression analysis, the drinking rate (t=2.38, p<0.05) and the speed of meals (t=-2.09, p<0.05) were found to be factors affecting obesity. These results will be useful as a basis for community's nutrition education and counseling program policy.

A60 class bulkhead penetration piece is a fire resistance system installed on bulkhead compartment to protect lives and to prevent flame diffusion in case of fire accident in ship and offshore plant. This study deals with evaluation on sensitivity of fire resistance performance and meta-modeling characteristics for A60 class bulkhead penetration piece using transient heat transfer analysis and fire test. The transient heat transfer analysis was carried out to evaluate the fire resistance design of the A60 class bulkhead penetration piece, and verified the analysis results via the fire test. In the sensitivity analysis, the bulkhead penetration piece length, diameter, material type and insulation density were applied to the design factors, and output responses were considered weight, temperature, cost and productivity. Quantitative effects on the output responses for each design factor were evaluated using design of experiment. Optimum design case was also identified to minimize the weight of A60 class bulkhead penetration piece while satisfying the allowable limits of output responses. From the design of experiment results, various meta-models such as Kriging, response surface method and radial basis function based neural network were generated. The design of experiment results were validated by the meta-modeling results. It was concluded that the radial basis function based neural network among the meta-models was able to explore the design space of the A60 class bulkhead penetration piece with the highest accuracy.

Methods of speed control of single-phase inuction motor include pole change and frequency control. Pole change method that is controlling the speed by converting the number of poles of the motor using only simple pole change device has lower capability of speed control than method of frequency control. However pole change method is more economical than method of frequency control because it has low manufacturing cost. In this paper we propose a method of improving the operating capability of 2-pole/4-pole using pole change method different from conventional method and the operating capability for each number of poles applied with the winding arrangement method is verified through finite element analysis.

In this work, we investigate the properties of molecular structure and boundary orbital functions of the AMDBP-AlH and Acetophenone and Isobutyrophenone, which are forms of alkoxy-amine-aluminum derivatives. Furthermore, we investigate the effect on the selective reduction of the final products (R), (S)-phenylethanol and (R), (S)-isophenylbutanol by calculating the stereoscopic and thermodynamic parameters of the transition state. Considering the three-dimensional molecular structural stability, the transition status of (S) types AMDBP-AlH and alkylphenone was found to be more stable, resulting in the selective reductions of AMDBP-AlH and alkylphenone from this result: (S)-Phenyl ethanol and (S)-isophenylbutanol was confirmed that the formation was advantageous.

Slewing bearings of special vehicle for anti-aircraft weapons can be successfully performed when the turret load and the impact load generated during shooting are combined in the process of performing the mission of the system equipment. In this study, the fundamental data for the design of resonance avoidance are obtained by comparing the exciting frequency of special vehicles with the natural frequency of slewing bearings.
As a result of the test, the primary natural frequency of the cornering bearing is approximately 36.25 Hz, and the secondary natural frequency is 103.75 Hz. In the case of first vibration mode, the resonance frequency domain, the error is about 3.9% compared to the analysis results and about 24.3% in the case of second vibration mode.

A key role of insulating curtains on greenhouse is the transmission of radiant energy from sun and the conservation of heat energy in greenhouse. Durability of curtains is mainly affected by various external factors that cause deformation and friction. Therefore, understanding on tribologic characteristic of covering materials is essential to prevent abrasion. The purpose of this study is finding optimal condition that can minimize the friction coefficient of materials. In this study, Pin-on-disk tribo-test is conducted to measure the friction coefficient with different applied load and sliding speed. The result shows that as the applied load increases, the friction coefficient also show a increasing tendency and when applied load is under 6N, there was no meaningful changes in friction coefficient. In addition, the largest friction coefficient was recorded at the point of 10N and 0,06 m/s.

Aluminium alloys have excellent strength and fatigue characteristics and are widely used as substitutes for steel in the aviation and ship automobile industries. Parts of the Al 7075 alloy used in the industry are subject to constant friction, damage and destruction at the contact surface between component and component. As a result, the need for functional materials suitable for specific applications is increasing. Surface coating technology is widely used to increase abrasion resistance and protect the material inside from the external environment. In this study, the abrasion resistance characteristics are considered when the DC magnetron sputtering power of the thin film is applied and the pressure is changed during the actual thin film deposition after argon is injected and plasma is formed. After that, the thickness of the thin film for each condition was measured, and the hardness was measured when the titanium thin film was formed. Then, the wear track was checked through the scanning electron microscope and the amount of wear was calculated. We have confirmed that abrasion resistance of Ti thin film decreases as deposition time increases and decreases when power is increased.

The purpose of this study is to use waste resources and improve the physical properties of concrete by crushing LCD waste glass for which an appropriate recycling method has not been developed and mixing it into concrete. LCD waste glass was pulverized into two sizes with an average particle diameter of 5㎛ and 10㎛ using a ball mill, and cement paste and concrete were produced by substituting 10% and 20%. Cement paste was used for XRD analysis, and concrete was used for compressive strength test, micropore structure test, and repid chloride penetration test. As a result of analyzing the hydrate composition by XRD, the reduction of calcium hydroxide due to LCD substitution was roughly confirmed, and in the result of compressive strength, concrete including LCD powder showed higher strength than OPC, and was up to 24% higher at 5㎛-20%. In addition, the replacement of the LCD powder reduced the size of the pores inside the concrete, and reduced the penetration rate of chloride. The reason for this result is believed to be due to the pozzolanic reaction caused by SiO2 contained in a large amount of waste LCD glass. Calcium hydroxide produced by the hydration reaction reacts with SiO2 to form C-S-H gel, and it is thought that the gel fills the voids in the concrete to increase the compressive strength and prevent the penetration of harmful ions.

Dual stator generator has excellent cogging torque characteristics and can generate a high voltage, thus minimizing the loss that occurs when boosting. Moreover, It has a high output ratio to the same volume because the voltage is generated from the inner and outer generator. Dual stator permanent magnet generator is operated in a single phase by connecting the inner and outer generators in series in order to secure high voltage, so it must be controlled in a different way from conventional three phase power conversion system. In this paper, we proposed a method of design and controlling a grid-connected power conversion system using a dual stater generator. The proposed method was verified through simulation.
